[TOMT] [BOOK] Fairies go to eternal sleepover to get teddy bear

This is how the book starts.

A group of fairies need a special teddy bear for some reason.

They go to a sleepover.

Everytime the sun comes up the girls go "we made it till the morning" and continue their sleepover.

The fairies find this unnatural since going to sleep together is one of the joys of a sleepover.

The girls have heavy eyebags due to sleep deprivation.

The girl who has the teddy bear is quiet and iirc, has short dark hair and big dark eyes.

Early to mid 2010s is when I read it but it was maybe published earlier.

Kind of appears to be Rainbow Magic series but searching Rainbow Magic sleepover doesn't give me the book.

If it is, I'd like the specific one.

I remember multiple fairies on the cover and one had a jeans skirt.
